We’ve got a Flicker in the neighborhood who has been rattling away on light posts for a couple weeks. Its quite an alarming sound. This morning while I was on the can, he landed on our roof at the bathroom fan vent, gave a quick announcement of his arrival, and went to work on the vent hood. It sounded like someone was shooting a machine gun on our roof. It was so cool, and it really amplified coming down the vent. I told him to be quiet because Michelle was sleeping, but he didn’t listen.
